I've been trying to stay away from these threads, but here goes.
I'm 18, and I'm starting out as a trainer. I didn't go to college, although I'm not saying I never will. I've had a lot of help, and a lot of advice. Usually, what I don't want to hear is exactly what I need. My best friends were pretty much born on horseback, and I respect their horsemanship highly. I grew up with them, on their farm, and that's where I learned to ride.
Fast forward to my 11th birthday. They bought me a horse. Finally, I had my own horse at my own house and I could ride every day. During the three years I owned that mare before her knee blew out and she had to be put down, I started working with kid's horses. Making bratty little ponies an acceptable mount. My next horse was a basically untrained Arab mare. She taught me so much about training. And humility. My parents split, and she was the collateral. I still rode as often as possible, and as soon as I was 18, I moved halfway across the country to work at a small barn. When, I decided to come home, I had several job offers, and I've landed an incredible job, working for an old teacher of mine, training out of her barn.
The point to all of that is this: you will get nowhere without connections, without people. If I had not spent years being as appreciative and hardworking at my friends barn, they never would have bought me a horse. If I hadn't been appreciative of that horse and worked my butt off every day, I never would have got another. Do you think my old French teacher would have hired me if I hadn't been a good student?
School matters. People matter. Be willing for the bad jobs, willing for the people who see your flaws, and willing for the people who help you out anyway. You cannot start out young by yourself. Build connections. You said you don't like people, but the horse world IS people. Horses are the easy part.
The people on this thread that are giving you such 'terrible advice' are some of the ones that have the most knowledge. If you're feeling ganged up on, consider that you are in the wrong.
